本文介绍了以3，5－二硝基苯甲酸为显色剂测定羟氯苯青霉素的简易快捷及选择性的方法。1实验所用仪器为P－EX3B型分光光度计，有关芳香族硝基化合物购自Aldrich，配成10－’mol／L的丙附溶液，该溶液需新鲜配制。羟氨等青霉素标准溶液：称取0．05g三水羟氨等青霉素，用5ml甲醇
This article describes the use of 3,5 - dinitrobenzoate as reagent for the determination of hydroxychlorpheniramycin quick and selective method. 1 The instrument used in the experiment was a P-EX3B spectrophotometer. The aromatic nitro compound was purchased from Aldrich to make a 10-mol / L propanol solution. The solution should be freshly prepared. Hydroxylamine and other penicillin standard solution: Weigh 0.05g hydroxylamine ammonia and other penicillin, with 5ml of methanol
